CAR-G UARD.

SPECIFICATION forming part of Letters Patent No. 550,069, dated November19,1895. Application filed October 6, 1894;. Serial No. 525,057- (Nomodel.)

To all whom it may concern! 7 Be it known that I, TIMOTHY A. DEVANE, ofthe city of Troy, county of Rensselaer, and State of New York, haveinvented a new and useful Improvement in Oar-Guards, of which thefollowing is a specification.

My invention relates to that class of devices which are attached to thefront ends of motor-cars and used to prevent persons fallin g in frontof them from being run over by the cars; and my invention has for itsobject the rendering of this class of devices more efficient and tobetter adapt them to the uses for which they are designed.

Acoompanyin g this specification to forma part of it there are twoplates of drawings containing four figures illustrating my invention,with the same designation of parts by letter reference used in all ofthem.

Of the illustrations, Figure 1 shows my invention as applied to thefront end of a car with the apparatus down and in a position for use.Fig. 2 shows it as applied to a mo tor-car and as drawn up and out ofposition at the end of a car. Fig. 3 shows in perspective the apparatusillustrated as detached from the car.

The several parts of the apparatus thus illustrated are designated byletter reference, and the function of the parts is described as follows.

The letter B designates the front sill of the car, 0 the front sill ofthe platform P, and B one of the car side beams.

' The letters T T designate side bars, of which there is one at eachside of the car-bottom, each of which bars has a horizontal track part25 and vertical end parts 25 15 with the upper ends of the latterattached to the car-bottom; and by means of which the side bars T aredepending therefrom, with its side bar parts parallel to the car sides.

The letter S designates a slide-block, of which there .is one used inconnection with each of the side bars T, and each of these slide-blocksis provided with tracking-wheels \V, which have grooved perimeters, andthese tracking-wheels are each hung in cars c and therein provided withbearings W, in which to journal and to run upon the upper side of thetracking-bars or side bars T T.

The letter D designates the guard proper, which preferably consists of acloth or wirescreen apron, secured to the frame F at its sides and outerend 6 and this frame is jogged at each side at J, so as to extenddownwardly, and back of where thus jogged, at each of its sides f thisframe F connects with one of the slide-blocks S at f by means of thepivot p The letter m designates a spring, which at its rear end rigidlyconnects with one of the slide-blocks, and which spring in each instance of its use from where thus rigidly connected is extendedfrontwardly to rest on top of one of the side bars T, so as to forceclownwardly the outer end of the frame F and its guard whenfrontwardly-projected beyond the car-bottom.

The letter S designates a spiral spring encircling each'of the side barsT between its slide-block S and its rear vertical end part 75 so thatwhen the frame F is moved rearwardly it is so actuated against the forceof the springs S The letter D designates a detaining and tripping dog,which is pivoted at d to the V-form depending leg U between its sides '0v said leg being attached at its upper ends to the under surface of thecar-bottom. This dog has a hook-form engaging end (P and a lever 61 atits inner end, and at the latter is connected to a vertical tripping-bar(1 the latter passing up through the car-platform and made with a headh, where it can be pressed down by the motorneers foot.

The letter S designates a spring connecting with the lever end of thedog and the under side of the car-platform.

The letter I designates a shoe-form spring that is projected from theouter end of the guard proper at each side, so as to pass down under thefront edge of the latter, and the function of this spring is to engagewith the ground when the guard is suddenly forced into position of useand thus prevent. the guard from abutting against any projection in thepavement.

The letter A designates a depending support on which the guard and itsframe rest when in use, and this support has a horizontal part (E, onwhich the frame rests, and depending arms a, which at their upper endsconnect with the under side of the car-platform.

As thus made, when the guard is not in use it is moved rearwardly andhooked onto the dog D with the parts in the position shown at Fig. 2.\Vhen aperson falls in front of the moving car or is likely to be struckby it, the motorneer presses down with his foot the tripping-bar d,which instantly releases the engagement between the dog and the frame F,rendering active the springs S and m,wl 1ich instantly force outwardlyand downwardly the frame F and its guard to rest on the support A, andwhereby the guard is in aposition at its outer end so near the ground asto interpose between the person in danger and the car-wheels.

In ordinary use the guard is in the position shown at Fig. 2, where itis out of the way, and when tripped for emergent useitis in the positionas shown at Fig. 1.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The combinatioiiwith the depending sidebars T, T, of the slide-blocksS, S, each having tracking rollers \V, mounted in ears 6, and adapted torun upon one of said side-bars; the springs S, S, of which there is oneoneirclin g each of said. side-bars back of its slide block; the frameF, pivoted at each of its rear ends to oneof said slide-blocks andprojected downwardly as extended forwardly; said. frame being providedwith an apron I), and shoe-form spring I; and the depending sup port A,on which said frame may rest when projected forwardly,substantially inthe mannor as and for the purposes set forth.

2. The com binationwith the depending sidebars T, T, of the slide-blocksS, S, each provided with tracking rollers \V, and mounted to run on oneof said side-bars; the frame F, pivotally connecting at each of itsinnerends with one of said slide-blocks and therefrom extended downwardly andforwardly and provided with an apron D, and the spring on, connectedrigidly at its inner end with each of said slide-blocks, with its outerfree end bearing upon the top of each of said sidebars; and thedepending support A, on which the frame and guard may rest whenprojected forwardly, substantially in the manner as and for the purposesset forth.

The combination with the frame F, pro vided with the guard or apron I),and constructed to be projected forwardly and downwa-rdly by the springsS, S, and m, and the slide blocks S, S, tracking on the side-bars T, T,substantially as described 01 the dog I pivoted at (F, to a hanger U,and having a hooleform end (Z and provided at its lever end with atrippingbar (l constructed and arranged to be operated substantially inthe manner as and for the purposes set forth.

Signed at the city of Troy this 5th day of September, 1894-, in thepresence of the witnesses whose names are hereto written.
